The invention relates to the thermopladzic duplication of sound records, particularly those consisting of a groove on the margin of a motion picture film. A is formed from the record groove, an is cemented to the motion picture negative film margin. This constitutes a talking picture negative film, as it contains a'negative picture record other records printed from it, and a soun record capable of to the picture record.

By operating the sound record molder con unction with a picture printer, a positive talking picture record is obtained eonof a picture film having a sound r'eco groove on its margin. The impm ing of the sound record tional time to that of the picture printing. Much labor and are thus saved, and anaccurateregisterofthetworecordsobtained, complete nism in their reproduction.

In practice many positives are produced from-the same negative to supply the various film exchanges. In order to facilitate this and also to afford convenience in handling and storing, and also to avoid error in printing sound and picture records in proper register, the patrix D is cemented to the negative film margin as shown in Figure 3. The utility of this will be-better appreciated by a study of the next figure.

Figure 4 is a view of a device intended to print a positive picture film from the negative film A, and at the same time impress the sound record in the film. The comined negative and patrix shown in Figure 3 is utilized in this apparatus. The reel 43 containing the positive film 26 is placed on the spindle 47, and the reel 44 containing the negative film A with its patrix Dis placed on the spindle 47. Ordinarily the celluloid faces of the films will be thus facing each other, but in case they are not, one or both reels may be turned around, and the film placed over the guiding roll 48 or 48. In any event the film will always be in a nearl drawing. The films pass between theheated rolls 40" and 40", where pressure is applied in order that the matrix may leave its impression in the celluloid. On their way to those heated rolls the films pass close to, or in direct contact with the metal chamber 41 containing steam or hot water. This insures the films being brought up to the plastic temperature without any necessity of reducing the usual printing speed of the picture printing portion of the apparatus. The films then take opposite directions and pass over the guiding rolls 45 and 45, and from thence to the picture printer. This latter is not all illustrated in the drawing, as any ordinary picture printer can be used here. The only alteration that is necessary is-to provide a groove 46 in all of its sprocket wheels as well as in the film gate. However, this may not be really necessary. This is to permit the passage of the patrix without any possible in ury to it. The main sprocket of the printer is shown at 25 with its guiding rolls 27 and groove 46. This sprocket is directly under the film gate of the printer. A cross section of the sprocket is also shown in Figure 5. This illustrates the manner in wh ch the patrix D fits into the groove. 46, while the gelatine faces of the negative film t and the positive film 26 are in contact durmg the "process of printing. After being i exposed in the film gate to light, the two films pass upwards and are wound upon their respective reels 1n the usual manner. The

with, if desired. One form of gearin vertical position as shown in the positive is then developed and is ready for the reproduction of both pictures and sounds. The sprocket 25 and heated rolls 40, 40 are rigidly connected by a suitable gearing, such as a belt, or sprocket chain, so that the film moves at a uniform speed The guiding rolls 45, 45 may, therefore, be dispensed is, however, illustrated. Two intermes ing pinions 25 and 25 are provided between the heated rolls and the sprocket 25 of the picture printer to insure the proper speed. Pinions 40 and 40 maintain the heated rolls in step. The rolls and chamber are connected by suitable piping to a source of steam, or other heating medium. In the drawing, the films are supposed to pass downward over the heated chamber and through the heated rolls; after this, they pass to the printer at the top. But the order can be reversed, if desired. In such case it would be necessary to provide the heated chamber below the rolls 40 and 40 Chambers may be provided in both positions and the steam or hot water turned into either according to the direction of motion of the film. It is desirable to heat the matrix as well as the positive film in order to obtain a more satisfactory impression. The power is preferably applied directly to the heated rolls, while they in turn drive the sprocket 25 of the picture printer.

By attaching the patrix directly to the negative and by further using the devices shown in Figures 4 and 5, the difficulties which would ordinarilv arise from the use of many feet of metallic or gelatine ribbon, are greatly minimized. Moreover, by means of identification marks on the films, strips and patrices when printing and impressing, the errors due to improper register will be practically eliminated, and perfect synchronism of picture and sound record secured. Also the apparatus combines several tedious and bothersome operations into one.

All positives required to supply film exchanges and the like have their picture record printed and sound record molded in one operation. It only remains to develop the picture record. If desired, during the latter operation, an adhesive water-proof tape can be cemented over the sound groove in order to protect it from the developing bath. Or, it may be coated with a wax-like substance. This is not necessary, however. By combining those various processes to produee unitary results, an immense amount of time and trouble is saved, and possibilities of errors reduced.
